  • Patent number: 8325315
    Abstract: Electric power is applied to a static charge dissipating line to apply a pixel voltage to a pixel electrode. A common voltage is applied to a common electrode. The common voltage is applied to the common electrode through a shorting pad formed on the lower substrate, or a probe is contacted to the common electrode to apply the common voltage to the common electrode. A liquid crystal layer is exposed to light while an electric field is formed between the pixel electrode and the common electrode, so that a cured reactive mesogen (RM) layer is formed on a surface of an alignment layer to pretilt liquid crystal molecules. A manner of applying electric power to the pixel electrode or the common electrode is facilitated and the pixel voltage or the common voltage may be uniformly applied. Therefore, the quality of a display panel may be improved.
